This paper describes the application a semi-parametric approach, a varying coefficients model (Hastie and Tibshirani, 1993), to implement an Oaxaca-Blinder type of decomposition in the presence of self-selection into treatment groups for a continuum of comparison groups. The flexibility of this...

We study the value premium using the multiples-based market-to-book decomposition of Rhodes-Kropf, Robinson, and Viswanathan (2005). The market-to-value component drives all of the value strategy return, while the value-to-book component exhibits no return predictability in either portfolio...

This paper examines the productivity growth of banks around the world. We opt for a novel parametric methodology that decomposes productivity growth into different components, and in particular into a ‘shadow' quasi-fixed input that would impose negative externalities to bank performance....

This paper shows how to decompose weakly stationary time series into the sum, across time scales, of uncorrelated components associated with different degrees of persistence. In particular, we provide an Extended Wold Decomposition based on an isometric scaling operator that makes averages of...

This paper considers Oaxaca-Blinder type decompositions with continuous groups. In particular, we decompose the differences between outcomes at a series of values of the group variable and at a particular value of the group variable into (i) a composition effect and (ii) a structure effect. The...
